1 Claim. 1

This invention relates to lamp shade structures. It is one of the objects of the invention to provide means facilitating the production of lamp shades in a simplified and efficient manner, re-

ducing the number of parts and the cost of lamp shades to a minimum, and permitting speedy assembly of lamp shades even by unskilled labor.

It is another object of the invention to provide means ensuring 'a sturdy body structure of the lamp shade having an inner lining layer and an outer surface layer, which body is drawn over the frame of the lamp shade and remains at all times in a substantially taut and preshaped condition, whether the shade body be made of silk, plastic, or plastic composition, or of like suitable stretchable material.

It is a further object of the invention to provide means affording firm anchorage of the lamp shade body on the frame without the use of stitches or other securing means passing through the material of the lamp shade.

Still a further object of the invention is to provide means rendering possible the employment of conventional frames on which the lamp shade will be located and afiixed and, if desired, for removal therefrom, tensioning of the lamp shade being had during mounting and assembly thereof in accordance with the stretchability of the material used so as to ensure always an aesthetic, tidy and pleasing appearance of the lamp shade.

With the above and other objects in view, the invention will be hereinafter more fully described and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out in the claim which forms part of the specification.

In the drawing:

Fig. 1 is a side-elevational view of the inner face of the lamp shade made in accordance with this invention and as seen in developed form;

Fig. 2 is a vertical, sectional view of the lamp shade on line 2-2 of Fig. 1 with the inner face thereof turned outwardly;

Fig. 3 is a partial and sectional view of the lamp shade of Fig. 1 in position on a frame and shown on an enlarged scale.

Referring now more particularly to the drawing, there is shown in Figs. 1 and 2 a lamp shade body I made in accordance with the invention and having the upper pair of panels ll, l2 and the lower pair of panels l3, Hi. The lower panels l3, I4 may be of different color and texture as those of the upper panels II, I2.

In order to manufacture this lamp shade which may be made from silk, plastic or plastic composition, or any other suitable stretchable material, upper panel II is joined to lower. panel I3 by means of a seam I 5'. In a similar manner, panel I2 is joined to panel I4 by means of seam I 6 and these pairs of joined panels 'I I; I3 and I2, I4 are joined together along their edges by means of seams I1 and I8 whereby a'lamp shade body I0 is obtained which has the inner lining l9 comprisingpanels IL; I2 andthe'outer lamp shade layer proper 20 comprising panels I3, 14. As can be seen in Fig. 3, the outer surface 20 of the lamp shade is somewhat shorter in length than the inner lining I9.

. The lamp shade frame structure 24 comprises an upper frame ring 2| ,a lower frame ring 22 and a plurality of wire or like members 23 interconnecting and spacing said rings 2| and 22 a predetermined distance from each other. Only one wire member 23 is shown in Fig. 3 for claritys sake.

In order to connect this lamp shade with the frame ring 22, an adhesive tape 25 is applied to ring 22. This adhesive tape or strip corresponds in height approximately to that of ring 22 and has the adhesive layers 25a and 25b. The layer 25b is placed in contact with the outer surface 22a of ring 22, whereas adhesive'layer 25a is employed for contact with and retaining the lowermost end 20;; of the outer lamp shade layer 20.

On the outer and lowermost surface 200. of the lamp shade layer 20 is subsequently placed a further adhesive tape 26 having the adhesive layers 26a and 2612, the latter covering the lower end 20a of outer lamp shade layer 20, whereas the adhesive layer 26a is adapted for contact with the lowermost end I9a of the inner lining layer I9. On the exposed surface of the lower end [9a of lining layer I9 is then placed and applied an adhesive masking tape or strip 21 which fixes in position by means of its adhesive layer 21a the extended lower end I9a of inner lining I9. This masking tape 21 may extend with its one end 28 toward the upper end 29 of outer layer 20 of the lamp shade body II).

On top of this masking tape 21 a covering in the form of a trim tape 30 may be placed having the adhesive layer 30a. This trim tape 30 has been shown in Fig. 3 in the state of being applied to masking tape 21 and is of such height so as to cover up the end 28 of masking tape 21.

The advantage obtained by the aforesaid structure is that when the tapes are of the pressureadhesive type, the lamp shade body ID with its inner lining layer l9 and its outer layer 20 may be conveniently afiixed to and for removal from the lamp shade structure 24.

It will be further realized from Fig. 3 that the longitudinal seam I1 is visible but may run lengthwise of a connecting wire member 23, if desired. It is further to be noted that the lamp shade proper can, at any time, in particular if it is subjected to atmospheric influences, be readjusted in position by means of the pressure-adhesive tapes which ensure easy mounting and assembly of the lamp shade having a tidy and pleasing appearance due to the fact that the same remains always in taut and pre-shaped condition.

As seen in Fig. 3, due to the fact that seams I5 and I6 are positioned at the inner circumference of and extend downwardly on upper ring 2I and further since lining I9 in assembled condition of the lamp shade body presses against seams I5, I6 and adjacent edges, upward shifting of the lamp shade body will be effectively prevented. 2

The inner lining layer I9 is longer than the outer surface layer 20, It will be apparent that the lowermost end of inner lining I9 will come to lie next to the outer surface layer 20. The lower circular end of the inner lining layer I9 will thus exert a pull on the outer surface layer 20 and will hold the same always in taut and desired position on the lamp shade.

It is further to be noted that the masking tape may be entirely eliminated and replaced by trim tape 30 or by any other suitable trimming.

Instead of using double-layer adhesive tapes 25, 26 it is further proposed according to the invention to first provide the lamp frame with a resinous lacquer or coating, such as, for example, a vinyl compound lacquer, to thereby obtain a resinous covering on said frame and in particular on the frame rings and then to bond the lamp shade body, when made from plastic or plastic composition, directly to said covering by suitable plastic adhesive, glue or resinous cements well known in the art.

It can thus be seen that therahas been provided in accordance with the present invention a lamp shade structure comprising a frame includ ing spaced apart and co-axially disposed ring members, a tubular lamp shade providing an inner lining layer and an outer surface layer and placed astride one of said ring members, said body terminating in two circular end pieces forming the extremities of said lining layerrand of said surface layer, respectively, and adhesive means fixing said circular end piece of said surface layer on said other ring member and said circular end piece of said lining layer onto said surface layer at said other ring member.

Although the invention has been described with reference to certain specific embodiments thereof, it is to be distinctly understood that various modiflcations and adaptations of the arrangements herein disclosed may be made as may readily occur to persons skilled in the art without constituting a departure from the spirit and scope of the invention as defined in the objects and in the appended claim,

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

Ina structure for a lamp shade having a frame including spaced apart ring members each with an outer surface; a single tubular-shaped body providing an inner lining layer and an outer surface layer for said lamp shade and terminating in two circular end pieces, said body being seated astride one of said ring members, and two adhesive tape means each provided with two opposite adhesive surfaces and each of a height corresponding approximately to the height of said other ring member, one of said tape means being located with one of said adhesive surfaces against the outer surface of said other ring member and bonding one of said circular end pieces of said lamp shade body to the other adhesive surface of said one tape means, the other adhesive tape means being positioned with one of its adhesive surfaces for contact with said one circular end piece whereby the latter is sandwiched between the other adhesive surface of said one tape means and said one adhesive surface of the other adhesive tape means, said other circular end piece extending below said other ring member and beyond said other adhesive tape means for position on the other adhesive surface of the latter and in overlapping relation thereto, whereby said lamp shade body is stretched over said one ring member and anchored in position on the other ring member, and an outermost strip adhesively secured to said other circular end piece and to an adjacent portion of said outer surface layer on which it is located in superposed position thereto.
